Several bug fixes & minor UI changes (#1466)

## Description
### Bug fixes
- Fixes a race condition crash when configuring subtitle styling before
libmpv is initialized
- Save the clicked item position on grid pages (#1428 & #1462)
- Fix querying the server every 3 seconds for transcode reason if the
video is direct playing


### UI changes
- Makes the title on grid pages slightly smaller
- Makes adjustments to the song list item on now playing so that no
space is used if there's no artist
- Use settings icon instead of triple dots on now playing page

### Related issues
See above

### Testing
Emulator, nvidia shield & google streamer

## Screenshots
